Q42.The statement that is INCORRECT about Ellingham diagram is (1) provides idea about the reaction rate. (2) provides idea about free energy change. (3) provides idea about changes in the phases during (4) provides idea about reduction of metal oxide. the reaction.
What This Question Tests
The question assesses basic conceptual understanding of Ellingham diagrams, specifically what information they provide and what their limitations are (they do not provide kinetic information like reaction rate).
